AMD FreeSync
FreeSync is the brand name for an adaptive synchronization technology for LCD displays that support a dynamic refresh rate aimed at reducing screen tearing.[1] FreeSync was initially developed by AMD in response to NVidia's G-Sync. FreeSync is royalty-free, free to use, and has no performance penalty.[2] As of 2015, VESA has adopted FreeSync as an optional component of the DisplayPort 1.2a specification.[3] FreeSync has a dynamic refresh rate range of 9–240 Hz.[2] As of August 2015, Intel also plans to support VESA's adaptive-sync with the next generation of GPU.[4]
Advantages
- Helps improve battery life by reducing the refresh rate of the panel when the screen is static (meaning, the previous frame was the same as the current one).[5]
- Ensures that the transition between refresh rate is seamless and undetectable to the user.
- Can be enabled by plug and play, making it transparent to the operating system and end user.
- Reduces implementation complexity of the Timing Controller (TCON) and panel by keeping the GPU's pixel clock rate constant and varying blank parameters.
- Dynamically adapts the display refresh rate to fixed video content frame rate for a power efficient and stutter-free video playback with anything over 30FPS.
- Dynamically adapts the display refresh rate to variable gaming content render for low latency and a smooth, virtually stutter-free gaming experience.
Disadvantages
- FreeSync cannot work with CRT-based displays
- Only works with DisplayPort.[6] A demo of FreeSync over HDMI has been shown at Computex 2015 in Taipei, for which AMD has used a modified version with proprietary protocols of the HDMI 1.4a standard. The result was identical as if DisplayPort was used, meaning the FreeSync technology could be soon implemented into the next HDMI standard.[7]
